A CORPORATION OF DELAWARE COOLING SYSTEM Original application filedMarch 27, 1928, Serial No. 265,136. Divided and this application filedJuly 29, 1930. Serial No. 471,526.

The present application is a division of the application of Alfred F.Masury and Charles Froesch, Ser. No. 265,136, filed March 27, 1928, forCooling system which relates to mountings for cooling systems in therear end of motor vehicles, the internal combustion engines of which arelikewise mounted at the rear. The present invention is specificallydirected to a vehicle body construction wherein provision is made formounting the foregoing mechanism suitably, at the same time providing amaximum body space and a rear window through which rear vision isafforded. In previous designs, the exhaust from the engines mounted inthis manner has been utilized to induce a flow of cooling air throughthe side radiators by means of Venturi throats formed in the exhaustline. This type of construction permits the entire power plant to bemounted as a unit at the rear of the vehicle and enables it to bemounted and dismounted quite readily.

In addition to the above features, the present invention includes aventilating system for the interior of the vehicle which enables air tobe drawn in through the radiator and discharged into the interior of thevehicle as warm air or, if desired, causes air from the interior to besucked out through the radiator and discharged from the exhaust stack.The latter path is for summer service while the former serves to supplywarm air for heating and ventilating the vehicle in the winter time.

Further objects will appear as the description proceeds and referencewill now be had to the accompanying drawings, wherein:

Figure l is a view in section taken on line.

Figure 2 is a view in section taken on line 22 of Figure 1, and lookingin the directi on of the arrows.

Figure 3 is a view in section taken on line 3-3 of Figure 1, and lookingin the direction of the arrows.

Referring to the above figures, a designates the body of a vehicleprovided with an internal combustion engine I). The form shown is of thesix cylinder type, the front three cylinders exhausting into the exhaustpipe 6 and the rear three into exhaust pipe 6 At the rear of thevehicle, a partition a forms a compartment for the power unit to bedescribed later.

At either side of the body a, apertures are formed to the rear of whichradiators (Z are mounted. Suitable connections (Z accommodate expansionof the radiator and preserve a weather tight joint between it and theside of the vehicle.

Secured to the rear faces of the radiators are housings e which areprovided with horizontal steps 6 to receive exhaust lines formed, in thepresent instance, as Venturi housings f. These housings communicate withjackets f about the exhaust pipe and manifold and provide a means forventilating the engine compartment as indicated by the solid arrowsabout the exhaust manifold in Figure 3. The housings 6 also communicatewith exhaust stacks g and permit the cooling air to be discharged intothe atmosphere after having passed through the radiators.

' The exhaust gases pass from the exhaust manifold it through exhaustpipes 72. into Venturi nozzles 2'. Being discharged from these nozzlesthey flow through successive Venturi throats 7', j and stack 9, helatter being formed with a restricted portion g to cause a furtherincrease in the velocity of the gases as they pass through the stack.

Through the upper portion of the radiators (Z a horizontal partition 03is formed, separating the cooling gases which pass above the partitionfrom those passing below the partition and flowing into the housings 6.Immediately above the housings e, auxiliary housings being curved toprevent drummin housings e are formed and the air flowing through theupper portion of the radiator and into housings is carried throughconduits and motor housing 6 into the interior of the vehicle asindicated in Figure 3. A small electric fan is mounted in the motorhousing a and creates a flow of air into the vehicle under the properconditions. When it is desired to draw air from the interior of thevehicle, pivoted louvres Z are closed, thus preventing air from beingdrawn from the exterior of the vehicle through the upper portion of theradiator 6. With the louvres closed, the Venturi throat 9' causes air tobe drawn through conduit 0 auxiliary housing 6 through the upper portionof the radiator and out through the stack is indicated by dot and. dasharrows tothe left of- Figure 1. shown as closed, which positioncorresponds tosumm'er operation, while those at the right of Figure 1are shown as open, corresponding to operating conditions in the wintertime. It will be quite apparent that in the summer time the electric fan70 will not be in operation.

The housing 6 is sectionalized for convenience in manufacture andassembly, and the stacks are formed with over-hanging lips to -form astorm-tight joint with the roof while permitting expansion andcontraction between these members. Suitable heat insulationm is providedon the partitions and walls which might readily transmit and radiateheat.

A very important feature of this invention resides in the formation ofthe walls as curved surfaces. The. housings e, 6 conduits,.radiatormountings, andwindow aperture n are all formed with curved walls, thuspreventing body drumming which results from the diaphragm action ofplain body walls under vibration. By providing two stacks at either sideof the vehicle they may be made small enough to accommodate a Windowopening a at the rear of the vehicle and between the stacks. Thedesirability of this element is quite apparent and its shape such thatits walls, being formed with curved surfaces, will not cause drummin Theinvention has been described in connection with the specificconstruction shown in the accompanying drawings, but its scope is nottobe limited, save as defined in the appended. claims.

We claim as our invention:

1 .A vehicle construction comprising a compartment formed at the rear ofthe vehicle, side radiators in the compartment, housings communicatingwith the radiators, exhaust stacks passing through the housings, andmeans to cause the exhaust gases to draw cooling air through theradiators and into the stacks, the walls of the compartment and Thelouvres at the left of Figure 1 are 2. A vehicle construction comprisinga compartment formed at the rear of the vehicle, side radiators in thecompartment, housings communicating with the radiators, exhaust stackspassing through the housings, a central opening through the compartmentbetween the housings, and a window in the rear of the opening, the wallsof the opening and housings being curved.
